CNS
Composed of midbrain, pons, and medulla oblongata
What is the brainstem?
Subsystems of the Autonomic Nervous System
What are Parasympathetic, Sympathetic, and Enteric Nervous Systems?
Artery credited with supplying anterior portion of the brain
What is the internal carotid artery?
Excitable cell with a selectively permeable membrane
What is a neuron?
-70mv or -65mv
What is resting membrane potential?
Part of CNS that controls muscle activity and processes sensory info from the PNS
What is the spinal cord?
System that regulates segment motion
What is the Somatic Nervous System?
Components of the Circle of Willis
Anterior, posterior, and middle cerebral arteries. Anterior and posterior communicating arteries.
When membrane potential becomes less negative
What is depolarization?
Determinants of action potential propogation
What are the myelin sheaths and axon diameters?
Location of the Primary Somatosensory Cortex
What is the post-central gyrus?
Location of sensory receptors and neurons for somatic nervous system
What are muscles, joints, and skin?
Supplies blood to the motor and sensory areas of whole body except the lower extremities
What is the middle cerebral artery?
Single presynaptic axon providing multiple EPSPs over short unit of time
What is temporal summation?
Region of brain that directs attention to the body or objects in extrapersonal space
What is the Parietal Association Cortex?
Where most pathways traveling from the periphery to the cortex synapse
What is the thalamus?
Monitors CSF at choroid plexus
What is the Autonomic Nervous System?
Symptoms include: contralateral weakness, loss of speech, and loss of gait
What are the signs/symptoms of an ischemic stroke?
Process of an action potential traveling down an axon, under myelin sheaths, and surfacing/regenerating at each node of ranvier
What is saltatory conduction?
Sums up IPSPs and EPSPs before action potential is ultimately triggered/hindered
What is the axon hillock?
Deficiency not reported in early case studies of individuals with frontal lobe damage
What is difficulty with intellectual functioning?
Cell bodies that some argue to be a part of PNS that control thalamus
What are basal nuclei/ganglia?
The 8 circumventricular organs that do not provide a BBB
What is subfornical organ, vascular organ of the lamina terminalis, median eminence, neurohypophysis, pineal gland, subcommissural organ, choroid plexus, and area postrema?
If you can describe how the concentration gradient, electromotive force, and electrical potential all interact to establish an RMP of a neuron, these 500 whoppers are yours bro
Good job
Vesicles on the periphery of neuron that contain neurotransmitters
What is the golgi apparatus?
